The domain name system (DNS)
A naming scheme is said to allow location transparency[26] if the scheme allows objects to be addressed without explicit knowledge of their physical location. For example, the U.S. phone number system is location transparent, as a caller does not need to know the whereabouts of the callee when dialing up. The U.S. postal address system, on the other hand, does not allow location transparency, since you must address the recipient with his/her physical address (excluding postal office boxes, that is). Consider each of the following naming schemes. For each, determine if it is location transparent? Justify your answer.
